Adams A4 Trumpet

Please contact your dealer for price and availability


The A4 is one of our most popular models in the trumpet line. This horn is a result of extensive collaborative work with Adams Performing Artist Amik Guerra. This is one of our heavier models. Featuring a 5.5-inch one-piece bell and also a heavy chassis this horn is an ideal choice for the soloist looking for an extremely rich, warm, fluid, and thick sounding horn. One of the things we stress about this instrument is the fact it will work in many different musical environments due to wonderful coloring and richness on this horn. While most people order this horn in the larger .470 (12mm) bore we do make a .460 (11.7mm) bore instrument on request for clients. Also available in this model is a shepherd´s crook model which allows for more personal expression in the dynamic and articulation palette.


Bell: Gold Brass - 140 mm
Bore: L 12 mm
Finish: Satin Lacquered
Gauge: 0,40

Build your own?

If you would like to configure your own A4 trumpet to your personal preferences, Adams will fully custom built your instrument. Please see below for custom options.

We offer our bells in a choice of gauge. In very general terms:

- The thinner the gauge of the bell results in a more energized, faster response.
- The ticker the gauge of the bell will result in more stability and density to the sound

Of course this in particular is very much specific to the overall build characterstics of the individual model of our Custom Series instruments. For example the A4 trumpet is primarily considered to be a "heavy" profile trumpet. We have found that a thinner gauge in the bell maximizes the whole tonal and articulation spectrum for this model.

For all of our Custom Series instruments we use brass bodies with nickel silver tuning slides. Meanwhile we offer a choice in bell materials, all listed below with their specific characteristics.

Yellow Brass

This bell is an excellent mix of materials for all round work as this material is very versatile. The sound is clear and brilliant at all dynamic levels, with a good core and great projection. This alloy is ideal for lead trumpet, commercial playing and studio work. Also a good choice for principal trumpet players in symphony orchestras or someone who is looking for good crispness to the articulated sound.

Gold Brass

Like the yellow brass bell this is a very versatile horn - a near perfect blend of warmth and projection. The gold brass brings a depth to the sound which is very smooth, rich and dark, however it is still a lively and agile trumpet. It responds quickly and has good projection without getting as brilliant as the yellow brass bell. We find it to be suited to a host of applications: be it in the jazz soloist, the crossover artist, the classical soloist, or someone who is looking for depth to sound while still retaining projection.

Red Brass

The Red Brass bell material is an ideal choice for the soloist who is looking for the richest, warmest, thickest sound available. Higher in copper content than our other two bell choices this provides the player with the smoothest transitions from note to note. Articulations are veiled (although with a lighter Red Brass bell option it is greatly improved) and sound shape is overall a bit wider in shape.

Sterling Silver

We do offer all Custom Series Trumpet Models with a solid Sterling silver bell. Sterling silver is a very versatile material but also much more dependent on the individual’s particular ability level. Therefore we recommend this bell option for the serious amateur or professional. The general characteristics are the bell is much darker and thicker when played at soft to medium volumes. When this bell is pushed the higher overtones are much more present and the result is a wonderful sound with great “sparkle.”

Next to the bell thickness (gauge) and bell material, we offer a choice in the finish of your Adams Custom Series instrument. These options slightly influence the sound color and for some it's just a matter of taste.

Raw Brass

This is actually no finish. The raw material of the instrument is only polished.

Silver Plated

This finish will liven and energize the sound slightly.

Gold Plated

This finish will leave the sound very similar to the original raw state.

Clear Lacquer

The instrument keeps the look of the raw material.

Gold Lacquer

A gold tone is added to the clear lacquer.

Copper Lacquer

A copper tone is added to the clear lacquer.


Colored lacquer which gives the instrument a typical antique look.
